DNA N4-cytosine methyltransferases (N4mC MTases) are a family of S-adenosyl-L-methionine (AdoMet)-dependent MTases. Members of this family were previously found to share nine conserved sequence motifs, but the evolutionary basis of these similarities has never been studied in detail. We performed phylogenetic analysis of 37 known and potential new family members from the multiple sequence align...

The basidiomycete genus Galerina Earle accommodates more than 300 small brown-spored agarics worldwide, predominantly described from the Northern hemisphere. The delimitation of species and infrageneric units hitherto has been based on morphological and, to some extent, ecological characters. In this study we have analyzed nuclear ribosomal LSU and ITS sequences to reveal infrageneric phylogeny...

The Stylasteridae, commonly known as lace corals, is a family of colonial calcifying hydrozoans mostly inhabiting deep waters. Stylasterids show cosmopolitan distribution but, in some areas, they are characterized by low species diversity, such the Red Sea, where only shallow-water has been reported so far. With this work, we provide first evidence deep-sea stylasterid NEOM region northern Saud...

The origin of the translation system is at the center of discussions about the evolution of biological systems. In this context, molecules of transfer RNA (tRNA) are highlighted due to its ability to convey the information contained in nucleic acids with the functional information contained in the proteins. Despite many characteristics shared among tRNAs in various organisms, suggesting a monop...

BACKGROUND AND AIMS The orchid genus Dichaea, with over 100 species found throughout the neotropics, is easily recognized by distichous leaves on long stems without pseudobulbs and flowers with infrastigmatic ligules. The genus has previously been divided into four sections based primarily on presence of ovary bristles and a foliar abscission layer. The aim of this work is to use DNA sequence d...

The spider mite sub-family Tetranychinae includes many agricultural pests. The internal transcribed spacer (ITS) region of nuclear ribosomal RNA genes and the cytochrome c oxidase subunit I (COI) gene of mitochondrial DNA have been used for species identification and phylogenetic reconstruction within the sub-family Tetranychinae, although they have not always been successful. The 18S and 28S r...

Chlorococcum is a coccoid green algal genus, which contains almost 50 species. The genus polyphyletic, but in traditional sense, the cells are and non-motile with cup-shape chloroplast vegetative stage, while spores have chlamydomonad appearance. They distributed worldwide mainly terrestrial habitats, biotechnological potential of several strains has been reported. In this study, three new from...
